On Energy Dissipation Theory and Numerical Stability for Time-Fractional Phase-Field Equations [PDF]

open access: yesSIAM Journal on Scientific Computing, 2018
For the time-fractional phase field models, the corresponding energy dissipation law has not been settled on both the continuous level and the discrete level. In this work, we shall address this open issue.
